My girl cousin was in her underwear and she didn’t tell me anything?

So I (20M) have a really good relationship with my cousin (18F) and she texts me every day when she wakes up and I just say ok or when I’m over at her house I hang out with her. Well a couple of days ago I was visiting and she texts me and I said oh ok want to hang out and she said yes so I go to her room and I knock until she says I can come in because she has her privacy and I want to respect her and she says come in and she always has a blanket on because she gets cold easily and so I talk to her and she invites me into her bed she has a king size bed and I was feeling cold so I lift the blanket up and because she has blackout curtains and it dark in her room I didn’t see anything then when I go to wake my uncle up for work he was already up and he comes into the room and says goodbye and says I got food go eat before it’s cold and she says ok let me get my shorts on and I’ll come and I was like what? And when I ask her about it she said it’s fine. I feel like I can get in trouble if I don’t do something about what’s going on

I think everyone misinterpreting what I’m saying I’m asking how should I go about what happened like bring it up with my uncle and aunt or just her and my aunt
